The front surface of the concave block 11 is penetrated by a pull rod 10 that is slidably connected. The outer wall of the pull rod 10 is sleeved with a spring 2 19. The spring 2 19 always pulls the pull rod 10 backward through its own elasticity to ensure that the rear surface of the pull rod 10 is always on the inner wall of the groove 2 when not subject to external force, thereby enhancing the stability of the limit. One end of the spring 2 19 is fixedly connected to the front surface of the concave block 11, and the other end of the spring 2 19 is fixedly connected to the rear surface of the pull rod 10. The front surface of the handle 5 is provided with groove 2, and there are multiple groups of grooves. The multiple groups of grooves 2 are provided to limit the handle 5 folded upward and downward to prevent the handle 5 from loosening. The rear surface of the pull rod 10 contacts the inner wall of the groove 2.

[0026] Furthermore, the bottom end of the outer wall of the connecting tube 2 is clamped with the shovel head 7 through the L-shaped clamping block 18. By clamping the rear end of the L-shaped clamping block 18 on the inner wall of the annular groove 2, the shovel head 7 and the connecting tube 2 can be connected together, which increases the convenience of disassembly and assembly. The bottom end of the outer wall of the connecting tube 2 is provided with an annular groove 2, and the left end of the upper surface of the L-shaped clamping block 18 is penetrated and fixedly connected with a cylinder 2 17, and the right end of the upper surface of the L-shaped clamping block 18 is penetrated and fixedly connected with a cylinder 16. A through groove 1 is provided at the top of the outer wall of the shovel head 7, and the cylinder 2 17 is rotatably connected to the inner wall of the through groove 1.

[0027] Furthermore, one end of the torsion spring 6 is fixedly connected to the outer wall of the connecting tube 2, and the other end of the torsion spring 6 is fixedly connected to the lower surface of the elliptical shell 3. The limiting rod 9 penetrates and is slidably connected to the front surface of the rectangular plate 8. The inner wall of the elliptical shell 3 has a certain curvature. When the elliptical shell 3 is rotated, the limiting rod 9 will move back and forth with the curvature of the elliptical shell 3 to ensure the quickness of opening and releasing the limit. The left end of the handle 5 rotates on the inner wall of the concave block 11, and the front surface of the limiting rod 9 contacts the inner wall of the groove one, and the rear end of the L-shaped block 18 contacts the inner wall of the annular groove two.

[0028] In the present invention, when in use, by pulling the pull rod 10 forward, the pull rod 10 will stretch the spring 2 19 forward until the rear surface of the pull rod 10 is completely separated from the inner wall of the groove 2, then the handle 5 can be pressed downward or pushed upward, and the handle 5 will rotate with the center of the circle of the rotating shaft 12 as the origin, so that the handle 5 can be folded for easy storage, and at the same time, the elliptical shell 3 is rotated, and the elliptical shell 3 will cause the torsion spring 6 to twist and deform, and at the same time, the spring 2 19 will slide backward along the curvature of the annular groove 1 on the front surface of the rectangular plate 8 until the front surface of the limit rod 9 Completely detach from the inner wall of groove 1, so that the slide bar 4 can be pulled to slide on the inner wall of the connecting tube 2, thereby shortening the connection distance between the connecting tube 2 and the slide bar 4 for storage, or extending and shortening the connection distance between the connecting tube 2 and the slide bar 4 for taking deep soil. When adjusted to a suitable position, the elliptical shell 3 can be loosened. At this time, the torsion spring 6 will drive the elliptical shell 3 to rotate back and reset through its own elasticity, and the limit rod 9 will also move forward along the curvature of the inner wall of the annular groove 1 and enter the inner wall of the groove 1, so that the connecting tube 2 and the slide bar 4 can be connected together.

[0029] When the shovel head 7 needs to be disassembled, it is only necessary to pull the limit column 15 upwards, and the limit column 15 will squeeze the spring 13 upwards. At the same time, the inner wall of the groove 3 on the lower surface of the limit column 15, the ring 1 is rotated at this time, and the ring 1 drives the L-shaped block 18 to rotate with the center of the circle of the cylinder 2 17 as the origin. At the same time, the right end of the L-shaped block 18 will rotate with the center of the circle of the cylinder 1 16 as the origin, so that the rear end of the L-shaped block 18 can be separated from the inner wall of the annular groove 2, and the connecting tube 2 and the shovel head 7 can be separated and installed. When doing so, it is only necessary to insert the connecting tube 2 into the inner wall of the shovel head 7, and then release the limit of the limiting column 15 on the ring 1, and then turn back the ring 1. The movement mode of the rear structure is the same as explained above, but the movement direction is opposite, so that the rear end of the L-shaped block 18 can enter the inner wall of the annular groove. At this time, loosen the limiting column 15, and the spring 13 will drive the limiting column 15 to move downward through its own elasticity, so that the lower surface of the limiting column 15 contacts the inner wall of the groove three, so that the connecting tube 2 and the shovel head 7 can be installed together.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
